Written premiums are the premiums recorded when policies are issued or renewed before those amounts are fully earned over the policy period.
Why It Matters
Written premium is a core operating measure because it shows sales and production volume. It helps readers distinguish growth activity from earned premium, which reflects premium recognized over time for the coverage period actually provided.
How It Works in Real U.S. Insurance Practice
When an insurer writes or renews a policy, the premium is booked as written premium. That does not mean the entire amount has been earned yet. As the policy period passes, premium is generally recognized as earned premium. The difference matters for financial analysis, growth measurement, and ratio interpretation.
Writers discussing books of business, line growth, or producer production often refer to written premium because it tracks business placed during the period. It is one of the quickest ways to describe production momentum. An agency can say it grew written premium by 12 percent, or a carrier can say commercial property written premium contracted after a tightening of appetite, even before the full earning pattern shows up in reported results.
That distinction matters because written premium measures volume, not earned performance. A book can show strong written growth while still producing weak results if claim experience, catastrophe exposure, or expense pressure deteriorates after the business is written.
Practical Example
If a carrier writes a large commercial property policy on December 1, the full premium may count as written premium in that period even though most of it will be earned across the following months of coverage.
The same idea matters in agency production. A producer may be praised for growing written premium this quarter, but management will still watch retention, loss ratio, and expense impact before deciding whether that growth improved the overall book.
Common Misunderstandings or Close Contrasts
- Written premium is not the same as earned premium.
- High written premium does not automatically mean the business is profitable.
- Written premium can grow quickly even while combined ratio deteriorates.
FAQ
Knowledge Check
If a carrier’s written premium rises sharply after a growth push, does that alone prove the new business is profitable?
No. Written premium shows production volume, not whether losses and expenses will later support good underwriting results.
